NUDIBRANCHIATA COLLECTED IN THE NORTH SEA 



Papillae long, stout, and irregular in outline, set in 9 transverse rows, 

 the first somewhat remote from the others and arising close behind 

 the rhinophores, thickest near the summit, and terminating somewhat 

 abruptly in a small point ; the inner rows held more or less curved 

 inwards ; 5 or 6 papilla in each row. 



The bases very pale, the " core " of^ light yellowish brown, irregularly 

 and indistinctly tinged with olive, an olive band near the tip, which 

 is white (due to numerous minute white crowded dots), or sometimes 

 tinged with olive or yellow. A bare space down the centre of the 

 back ; posterior region pinkish fawn. Body rather narrow, foot as in 

 Alder and Hancock's plate. Tail shorter than their figure. 



The white spots on the body well marked, those on the rhinophores 

 and papillcC less so. 



The specimen was living on a branch of Antcnnnlaria ramosa grow- 

 ing upon a stone brought up by the conical dredge. The hydroid was 

 crowded with yellow gonophores, and the animal was by no means 

 conspicuous when extended with the body parallel with the stem, the 

 general colour and form of the papillae approximating closely to what 

 was undoubtedly its natural environment.

 Some variations were observable in the colours of the body and papillae. 

 In the younger specimens the yellow band near the tip of the 

 papillae was paler than in the adults, and in one case it was absent 

 from some of the papillae, though present in others ; when absent the 

 whole tip was white.
